Microplastics found in Arctic snow

Pieces of microplastic were found in arctic snow just weeks after World Meteorological Organization and Copernicus Climate Change program announced July 2019 was the hottest month ever recorded, period.

Microplastics are falling from the sky via atmospheric transfer and are landing in remote places in the Arctic in substantial amounts, according to a study from Science Advances published on August 14. Scientists studied ice floes in Fram Strait, an unpopulated expanse of ocean near Greenland, and compared it to populated European sites. The study showed that the populated areas had a higher concentration of microplastics, but that the amount in remote areas was still high.

According to a report from National Geographic, scientists from Germany’s Alfred Wegener Institute for Polar and Marine Research and the Swiss Institute for Snow and Avalanche Research said the amount of microplastics in the atmosphere could potentially pose a risk to public health. Temperature fluctuation among other things can cause plastics to break down into smaller fragments, which then produces the microplastics.

These institutes have been studying microplastics in the Arctic region since 2002 and have noticed drastic increases over the years. In the Arctic water column they found 6,000 microplastic particles in every 2.2 pounds of mud. In every 34 ounces of melted sea ice, they found 12,000 particles.

The report from Science Advances projects annual waste production to reach 3.4 billion MT in the next 30 years. Additionally, mismanaged plastic waste could reach 265 million MT by 2060. The report also highlights the fact that microplastics are ubiquitous in almost all ecosystems – freshwater, urban areas, terrestrial areas – because plastic is designed to be durable.
